How Has Australia's Population Changed

The social phenomenon of our population structure is gradually styling a force of change in Australia. Australia is made up of just over 20million people, which is relatively small by world standards. Australia’s population has changed over years impacting greatly on our continents structure, ethics, migration and the Indigenous.

Natural increase and net migration
• The population of Australia has changed rapidly over the last century
• Two main reasons being Natural increase and Migration. Both of these have been a major component of Australia’s population growth.
• Migration to Australia began more than 50 000 years ago with the Australian Aboriginals and Torres straight islanders first making contact.
• Net overseas migration currently contributes to about 60 per cent of Australia's population growth and has outstripped the natural increase population.
• The baby boomers during 1950 after WWII changed our continents population hugely impacting the society big time.
• Later in the 1970-1980’s the stoppage of large amounts of births had decreased due to fertility and mortality increasing.
• Factors for these included: contraceptive methods, increased cost of raising children, advances in medicine and improvements in lifestyle.

Structure, ageing population
• The structure of Australia’s population has greatly changed, enforcing an ageing population.
• Our population structure has mostly changed due to Australia having a low crude death rate; low crude birth rate, high life expectancy and the children of the baby boom are retiring.
• Implications of the ageing population will largely affect the way Australia works. As more people retire, the will be a reduction in human work. The consequences of an ageing population involves the government paying for health and welfare, tax payers paying more for pensioners, and a greater demand for services.
